IPC: F15B11/072
Filed: 1966-10-18
Abstract: 1,167,522. Hydraulic jacks. WALKER MFG CO. Oct.18, 1966, No.46500/66. Heading F1P. A hydraulic jack 10, Fig.1, includes a lever 18 that is pivotally supported by a pin 20 in a carriage 12 having wheels 14 and is actuated by a hydraulic motor 24 of the piston-and-cylinder type so that a platform 22 at its free end is first brought into abutment with the load 50 when a control lever, or handle, 78, Fig. 5, on a valveassembly 48 is angularly-displaced downwardly and the platform is subsequently raised to effect elevation of the load by further downward displacement of the control lever, the platform 22 being depressed by the load when the control lever is released. The valve-assembly comprises a pair of valve-members, or portions, 108, 110, Fig.4, having stems 104, 106 biased upwardly by compression-springs 116, 118 whereby vertical bores 90, 92 are normally closed to prevent compressed air in a conduit 100 entering either of two conduits 44, 136 through bores 134, 132, respectively. The stems 104, 106 of the two valve-members differ in length so that when the control lever 78 is pressed downwardly by the operator first one stem is depressed and then both of them together. When the stem 104 is depressed, compressed-air is admitted to a hydraulic-fluid reservoir 28 through the conduit 136 to force the hydraulic fluid into the motor 24 and bring the platform 22 into abutment with the load; and, when the stem 106 is also depressed, compressed-air enters pneumatically-operated pumping-means 30 through the conduit 44, which means pumps hydraulic fluid from the reservoir into the motor 24 to effect elevation of the load 50. When the control lever 78 is released, the valve-members 108, 110 are returned to a closed position and compressed-air remaining in the reservoir 28 is vented to the atmosphere through a bore 144, Fig. 5, which is closed by a spring- loaded spherical valve-member 148 when the control lever is depressed. The valve-assembly 48 is lodged between portions 54, 56 of a manipulating handle 16, which is attached to the carriage 12, the housing 52 of the valve-assembly and the control lever 78 being supported by a U-shaped bolt 58 and an associated plate 68 that together grip said portions of the handle 16.

Abstract: 1,274,727. Shrink-wrapping pallet loads. WELDOTRON CORP. 22 Sept., 1969 [7 Oct., 1968], No. 46628/69. Heading B8C. In a method of wrapping a pallet loaded with stacked boxes 12 the loaded pallet is fed along a conveyer 18 to a sensing device 26, 27 which, as it detects the leading edge of the load, operates, through an electrical circuit, Fig. 3, not shown, to cause a sheet of heat shrinkable film 28 to pay out at the same rate as the load and drape over the top surface 17 of the load. The sheet 28, which is unwound from a supply roll 31 and passed between guide rollers 32a, 32b, is automatically severed by a cutting device 33 when the trailing edge of the load is sensed by the device 26, 27. Another sheet of heat shrinkable film, not shown, may be unwound from a supply roll rotatably mounted under the conveyer 18 to provide a covering of sheet on the bottom surface of the pallet load. Alternatively, individual sheets may be placed over each pallet before the boxes 12 are stacked. The pallet load assembly is then moved forward into a curtain of heat shrinkable material formed by webs 13, 14 unwound from vertically journalled supply rolls 21,22 respectively and joined by a vertical weld 14, the webs being joined together and severed on the trailing face of the load by a pair of sealing and cutting jaw assemblies, not shown, to form a vertical sleeve 16 about the pallet and simultaneously forming a new curtain of heat shrinkable material for a succeeding loaded pallet. The loaded pallet is finally forwarded into a heat-shrinking and fusing apparatus 34 where the portion of the sleeve 16 which extends above the top surface of the load is mechanically locked and fused to the top sheet. The sides of the bottom sheet (35), Fig. 5, not shown, may be pulled upward around the bottom layer of the boxes before the pallet is passed into the apparatus 34. In other arrangements a sheet, or crossed strips of heat shrinkable material may be interposed between each, or every other layer of boxes, and heat sealed to the sleeve.

Title: Transmission line seismic communication system
IPC: G01H1/00
Filed: 1974-10-30
Abstract: 1465306 Seismic exploration GLOBE UNIVERSAL SCIENCES Inc 30 Oct 1974 [5 Nov 1973] 46946/74 Heading G1G [Also in Division G4] In a seismic communication system, a central station sends a strobe burst over a continuous twinlead transmission line to a plurality of remote stations all of which respond by subsequently inserting digitized seismic data on to the line at successive time slot intervals. At each remote station, detection of a pilot signal switches on the power to the station, power being switched off again on detection of an inordinate gap between strobe bursts. The strobe burst is a pseudo-random bit pattern in bi-phase-mark form which is decoded from this form and recognized in each remote  station as it goes down the line, to synchronize the station by selecting the next appropriate output  signal of a crystal clock in the station and starting a time slot counter, the station being controlled so that outputs from three geophones at the station are digitized in turn into gain and mantissa portions which are stored together with header information, overall gain, in one of two memories, used alternatively, encoded into Miller code and applied to the line after the strobe burst and any such data from preceding stations on the line. Parity bits are also sent. The remote stations are arranged in a linear array, the central station being alongside one of them to divide the array into two sections which use respective transmission lines, the central station having two transmitters and two receivers. Shot points are provided near at least some of the remote stations and when the active shot point and active remote stations are to be advanced along the sequence of points and stations, "roll along", a calculator in the central station, under operator control, advances the station number and time slot number assignments. The data from the remote stations is supplied via a processor to one of two memories, used alternately, as the other memory is read out via a re-multi-plexer and recorded on tape. The tape can be played back via a D/A converter and de-multi-plexer to a camera. The tape recorder can be by-passed. A display is provided of the system. The shots can be triggered from the central station by radio or via transmission lines, perhaps by a coded signal.
